Mark,

I've got you beat, my old bottle says April 2018.
I haven't used it for a while and would certainly test it before using it.
Glue some scraps and break apart to see if the glue fails.

If you are worried about the strength and have a critical joint to glue
then buy a new bottle. But save the old for less structural applications.

I try to keep a fresh "full" strength bottle and an expired one. When I
get a new bottle the former fresh one gets downgraded for the less
critical applications and the oldest one goes in the trash.
